Towards an Integrated Knowledge-Base Management System: Overview of R&D on Databases and Knowledge-Bases in the FGCS Project.
Kazumasa Yokota, Hideki Yasukawa · 1992
Knowledge representation languages and knowledgebases play a key role in knowledge information processing systems. In order to support such systems, we have developed a knowledge representation language, QUI- XOT E, a database management system, Kappa, as the database engine, some applications on QUIXOT E and Kappa, and two experimental systems for more flexible control mechanisms. The whole system can be considered as under the framework of deductive object-oriented databases (DOODs) from a database point of view. On the other hand, from the viewpoint of the many similarities between database and natural language processing, it can also be considered to support situated inference in the sense of situation theory. Our applications have both of these features: molecular biological databases and a legal reasoning system, TRIAL, for DOOD and a temporal inference system for situated inference. For efficient and flexible control mechanisms, we have developed two systems: cu-Prolog based ...
